Detecting a particular word in a cell vector

3 views (last 30 days)
Dear all,
I have a matrix whose first column is :
'MAR'
' POPSIZE'
'OTHTOTAL'
' CONIZE'
' POPIZE'
'MAR'
' POPULAR SIZE'
'OTHOTAL'
' CONSIIZE'
' POPUZE'
'MAR'
'PRODGORY'
I want to detect if the above column contains the string element ‘MAR’
thanks

eg
A = {'MAR'
' POPSIZE'
'OTHTOTAL'
' CONIZE'
' POPIZE'
'MAR'
' POPULAR SIZE'
'OTHOTAL'
' CONSIIZE'
' POPUZE'
'MAR'
'PRODGORY'}
out = any(ismember(A,'MAR'));
or
out = any(strcmp(A,'MAR'));

see if any(strcmp(M,'MAR')) works for you, if there is MAR it shows 1 else 0
Example: If M = {'MAR'
'POPSIZE'
'OTHTOTAL'
' CONIZE'
' POPIZE'
'MAR'
' POPULAR SIZE'
'OTHOTAL'
' CONSIIZE'
' POPUZE'
'MAR'
'PRODGORY'}
use strcmp(M,'MAR')

I would use a regexp. http://www.mathworks.com/help/techdoc/ref/regexp.html Perhaps with a 'match' option, depending what you want as an output.
test = { 'MAR'
' POPSIZE'
'OTHTOTAL'
' CONIZE'
' POPIZE'
'MAR'
' POPULAR SIZE'
'OTHOTAL'
' CONSIIZE'
' POPUZE'
'MAR'
'PRODGORY'};
regexp(test,'MAR')
